MEXICO CITY – A magnitude-5.8 earthquake rocked the southern Mexican state of Oaxaca on Wednesday, but no injuries or serious damage have been reported, the National Seismology Service said.

The earthquake occurred around 5:06 a.m. and its epicenter was located 27 kilometers (about 17 miles) north of the city of Matias Romero at a depth of 121 kilometers (75 miles), the service said.

The quake was felt in the states of Puebla, Veracruz, Tabasco and Chiapas, but few Mexico City residents felt the temblor, officials said.

“The inspection protocol has concluded, no evacuations have been observed, for the time being there is no damage nor anyone injured,” Mexico City Mayor Miguel Angel Mancera said in Twitter post.

Mexico, one of the countries with the highest levels of seismic activity in the world, sits on the North American tectonic plate and is surrounded by three other plates in the Pacific: the Rivera microplate, at the mouth of the Gulf of California; the Pacific plate; and the Cocos plate.

The Cocos tectonic plate stretches from Colima state south and has the potential to cause the most damage since it affects Mexico City, which has a population of 20 million and was constructed over what was once Lake Texcoco.

The magnitude-8.1 earthquake that hit Mexico City on Sept. 19, 1985, was the most destructive to ever hit Mexico, killing some 10,000 people, injuring more than 40,000 others and leaving 80,000 people homeless.

The most recent powerful quake to hit Mexico was a magnitude-7.6 temblor that rocked Colima on Jan. 21, 2003.
